Abstract

L'invention concerne un procédé de séparation du fer à partir d'une phase organique liquide initiale contenant de l'uranium, et du fer, dans lequel on met en contact la phase organique liquide initiale avec une solution aqueuse dite solution aqueuse de déferrisation, moyennant quoi le fer passe dans la solution aqueuse pour former une phase aqueuse liquide finale, et l'uranium reste dans la phase organ!que liquide initiale pour former une phase organique liquide finale dite phase organique déferrisée; ledit procédé étant caractérisé en ce que la solution aqueuse de déferrisation contient un acide inorganique et de l'uranium, et ne contient pas de fer. L'invention concerne, en outre, un procédé d'extraction de l'uranium à partir d'une solution aqueuse d'un acide inorganique contenant de l'uranium et du fer.
